I also love short-ish games, so hopefully one of these strikes your fancy. You didn’t specify a preferred genre or other games you liked, so I’m going to just throw some out there:
Adventure/Puzzle
Stacking - fun adventure puzzle game based on matryoshka dolls
Little Nightmares - fantastic puzzle game stuff great atmosphere and horror elements; similar to INSIDE and Limbo
Abzû - underwater exploration with light puzzle mechanics
Ys 1 and 2 - pretty old, but it’s my favorite Ys game; Ys Origin is a bit newer, but also a bit longer (~11 hours per playthrough, need 3 for full story, but each plays differently)
Puzzle
Manifold Garden - puzzle game where you manipulate gravity
Hexlogic - sudoku-like
SUPERHOT - shooter that plays like a puzzle game
Magrunner - just ignore the story, the puzzles are pretty good
Portal - the OG puzzle game, must play if you haven’t; second is about twice as long
ARPG/Souls-like
Death’s Door - just started, but it’s looking good
Ittle Dew - Zelda-like with lots of satire about the genre
Furi - boss rush only
Titan Souls - boss rush, but both you and the boss has 1HP
Narrative heavy
Telltale Batman or The Walking Dead - narrative heavy game with walking simulator sections; choices matter (but not a ton); great if you want a decent interactive story
What Remains of Edith Finch - explore your old home to learn everyone’s secrets
Oxenfree - explore Island to uncover its secrets; replay value for alternate endings
Metroidvania
Headlander - Metroidvania where you play as a disembodied head that can attach to other bodies
Ori and the Blind Forest
Point and Click
Darkside Detective - point and click with a great sense of humor
Broken Age - you’re a virgin about to be sacrificed, and you’re not sold on the idea
Deponia - earth is completely wrecked, and you want off; quite funny
AAA/high production value
Ryse: Son of Rome - not amazing, but a pretty satisfyingly average experience
Call of Juarez: Gunslinger - shooter a bit after the US civil war
I have more, just let me know what you like and I can try to give more recs.
